Bass players (prog- hard rock-oriented)

Keep an eye peeled for a disc by bassist Alberto Rigoni called Rebirth. I picked this up yesterday and it's got some interesting guests: Gavin Harrison plays drums on three tracks, Michael Manring guests on bass on a couple tracks, as well as a few other players (keyboards, vocals) sprinkled thru the disc, including several other bass players, up to 3 on a track.

It's not all hard rock, there's a couple of bass-only or keyboard-only tracks, but I was gravitating towards the rockier numbers, myself.
